Example of simplexml_load_file function usage in PHP, simplexml

This example describes the use of Simplexml_load_file functions in PHP. Share to everyone for your reference. The specific usage analysis is as follows:

In PHP, after the simplexml_load_file () function loads an XML document into an object, we can use the object returned by this function to do the related operations, and let's look at a few test examples.

example, the XML file code is as follows:
Copy CodeThe code is as follows: <?xml version= "1.0" encoding= "Iso-8859-1"?>

George
John
Reminder
Don ' t forget the meeting!

The PHP code is as follows:
Copy CodeThe code is as follows: <?php
if (file_exists (' Test.xml '))
{
$xml = simplexml_load_file (' Test.xml ');
Var_dump ($xml);
}
Else
{
Exit (' Error. ');
}
?>

The results of the run output are as follows:
Copy CodeThe code is as follows:
Object (SimpleXMLElement) #1 (4) {
["To"]=>
String (6) "George"
["From"]=>
String (4) "John"
["Heading"]=>
String (8) "Reminder"
["Body"]=>
string "Don ' t forget the meeting!"
}

If there is a "iciba.xml" file, its contents are as follows:
Copy CodeThe code is as follows: <?xml version= "1.0" encoding= "UTF-8"?>

Sky

Array;array;

The church tower stood against the sky like a finger pointing towards heaven.
The spire of the church is like a finger pointing to the sky against the sky.


A balloon floated across the sky.
The balloon floated across the sky.


A bolt of lightning lit up the sky.
(together) lightning illuminates the sky.


A Bright Moving object appeared in the sky at sunset.
Sunset, a moving shiny object appeared in the sky.


A bright rainbow arched above.
A curved bright rainbow hangs in the sky.



In the PHP language we can get the values we want in the following ways:
Copy CodeThe code is as follows: <?php
$xmldata = simplexml_load_file ("Iciba.xml");

Header ("content-type:text/html; Charset=utf-8 ");
Print_r ($xmldata); The first part

$listcount = count ($xmldata->sent);

for ($i =0; $i < $listcount; $i + +) {//Part II
$dictlist = $xmldata->sent[$i];
echo "
Example: ". $dictlist->orig;
echo "
Translation: ". $dictlist->trans;
}
?>

The "first part" will output:
Copy the Code code as follows:
SimpleXMLElement Object
(
[@attributes] = = Array
(
[num] = 219
[id] = 219
[Name] = 219
)

[Key] = Sky
[pos] = simplexmlelement Object
(
)

[Acceptation] = Array;array;
[Sent] = = Array
(
[0] = = simplexmlelement Object
(
[Orig] = The church tower stood against the sky like a finger pointing towards heaven.
[trans] = The spire of the church is like a finger pointing to the sky against the backdrop of the sky.
)

[1] = = SimpleXMLElement Object
(
[Orig] = A balloon floated across the sky.
[Trans] = balloon floats across the sky.
)

[2] = = SimpleXMLElement Object
(
[Orig] = A bolt of lightning lit up the sky.
[Trans] = (together) lightning illuminates the sky.
)

[3] = = SimpleXMLElement Object
(
[Orig] = A Bright Moving object appeared in the sky at sunset.
When [trans] = sunset, a moving shiny object appeared in the sky.
)

[4] = = SimpleXMLElement Object
(
[Orig] = A bright rainbow arched above.
[trans] = a curved bright rainbow hangs in the sky.
)

)

)

"Part Two" will output:
Copy the Code code as follows:
Example: The church tower stood against the sky like a finger pointing towards heaven.
The spire of the church is like a finger pointing to the sky against the backdrop of the sky.
Example: A balloon floated across the sky.
The balloon floated across the sky.
Example: A bolt of lightning lit up the sky.
(a) lightning illuminates the sky.
Example: A Bright Moving object appeared in the sky at sunset.
Translation: When sunset, a moving shiny object appeared in the sky.
Example: A bright rainbow arched above.
Translation: A bright rainbow hangs in the sky.

For example, a more in-depth traversal of the output generated table, the code is as follows:
Copy the Code code as follows: Eader ("content-type:text/html; Charset=utf-8 "); Set encoding
$xml = simplexml_load_file (' A.xml '); Loading the XML file $lists is the same as the root node of the XML file
echo $xml->company. "
";
echo $xml->town. "
ID: ";
echo $xml->town[' id ']. "
Parent: ";
echo $xml->town[' parent '].
";

echo "
Loop read:
";
foreach ($xml->user as $users) {//has more than one user, gets an array, loops out
echo "-------------------
";
echo "Name:". $users->name. "
";
echo "Number:" $users->age. "
";
echo "Gender:". $users->age[' sex ']. "
";
echo "Serial number:" $users->height. "
";
}

echo "
Loop read:
";
foreach ($xml->town as $towns) {//has more than one user, gets an array, loops out
echo "-------------------
";
echo "ID:". $towns [' id ']. "
";
echo "Attribution:". $towns [' Parent '].
";
echo "region:". $towns. "
";
}
